Ulmus americana

27 equations apply to this species, 18 fitted on it directly. Each output lists them most specific first: fitted on this species, then on a variety of it, then pooled fits that included it, then its genus and its family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first.

Wood density 0.54 g/cm³, estimated from 34 samples in 5 studies by the Global Wood Density Database v.2 (Fischer et al. 2026, CC BY 4.0).
